Jan August 06, 2025 for Model Number LDS6040ST LG Dishwasher Model: LDS6040ST S/N 304KWBYB3469 Developed loud noise while operating at high speed, stopped working, error code LE. Also, leaking onto heating element from above.
1 Answer Hello Jan, and thank you for your question. The noise can be caused by a failing circulation motor 4681ED1004E or debris depending on what type of noise it is. In regards to the leak, the sump seal (only available as part of the sump and motor assembly AJH72949004), safety switch EBF61334501, or one on the hoses on the sump assembly could be leaking. To identify the specific component, the dishwasher would need to be inspected for indications of the origin of the water leak. Read More...
Jett July 22, 2025 for Model Number LDF6920ST when start, the water fills in and stops. Then I do not hear the washing sound but the machine stay as it is. it seems the water is not feeding up to the any deck. Will circulation pump motor change resolve this issue? 4681ED1004A
1 Answer Hello Jett, and thank you for your question. While the circulation pump 4681ED1004B could be the cause of the failure, there are a few checks you can do to help confirm it. First, check whether the motor is making a humming sound. If it is, inspect the impeller to see if it's blocked or damaged. If the impeller is clear and intact, the circulation pump is likely the issue. If there’s no hum at all, turn off power to the dishwasher at the breaker and inspect the wiring between the control board and the motor for any loose or damaged connections. If the wiring checks out and there are no error codes present, the problem may lie with the main control board 6871DD1006Q. Read More...
Jim June 25, 2023 for Model Number LDS5040ST i have no or very low water presure and the arms dont turn but the curk pump does run.is there a test i can do to see if its bad
1 Answer Jim, If the washer has water in the tub and it is not circulating when the circulation pump is running then you will need to disassemble the pump and check for debris blockages and impeller damage. Read More...
Mariana Molosag August 09, 2021 for Model Number Ldt5678st My dishwasher keeps getting the BE error code right before the drying cycle. I tried everything, levels, cleaned it with milk bowl, nothing works. Please advise what it should be
1 Answer Mariana, The bE error code will represent a sudsing error in which you will want to try to let the dishwasher fill with water then put some vegetable oil, vinegar or salt in the tub and let the unit run. It sounds like there may either be too much detergent usage or possible the wrong detergent put into the unit. Make sure that there was no regular dish soap put in the rinse aid by accident.

Wayne February 13, 2021 for Model Number LG LDF9810ST I usually start my dishwasher at night before going to bed and unload it in the morning allowing all night to dry the dishes. This morning as I began to unload the dishwasher I noticed the silverware and dishes were still wet. Upon checking all the other dishes I noticed the detergent pod still lying in the bottom of the machine still undissolved. I decided to start another cycle to see what was going on. I pressed the power button, selected a normal cycle and closed the door. The unit soon began pumping out what small amount of water remained in the bottom. Soon afterwards I could hear the water filling the dishwasher. All this seemed normal. After that I could hear nothing. Usually I can hear the motor softly running and the swishing of the sprayer arms. I could not see any error codes come up. I thought it could be the circulating motor (maybe the diverting motor?), I assumed the dishes could be wet due to steam and humidity in the dishwasher regardless of whether the sprayers were working but I still was puzzled by the dishes not being dried unless I am having more than one issue happening at the same time. I also did a reset of the dishwasher to no avail. Any help would be greatly appreciated!
1 Answer Wayne, it would be recommended that the circulation motor is tested for incoming voltage to identify if the main control EBR38144406 (part has been discontinued by the manufacturer) is sending voltage to the motor. If not, the main control has failed and could cause many issues, including improper heating and drying. Read More...
Patrick C November 24, 2020 for Model Number LDS5811ST-02 MY dishwasher makes a grinding noise when the wash cycle runs. I entered the test mode to test the n32 (wash pump) and the sound is not reproduced on this test, i hear a little high pitch sound but no grinding. What can cause this sound then? I’m confused
1 Answer Patrick, You will want to check down inside the pump and see if there may be something caught down in there. It is possible also that the impeller is not turning properly which could lead to noise when it is filled with water. if the impeller is slipping. Read More...
Scott April 12, 2020 for Model Number LDS5540ST My dishwasher has a stripped out screw head (from previous home owner) for the circulation motor. I was going through the washer to troubleshoot the top spray arm not functioning correctly. My problem was just a lot of debris in the bottom of the sump assembly. I am wanting to replace the agitator and sump housing but I cannot remove the screw for the circulation motor. Any chance I can get one here since it’s a left hand thread screw?
1 Answer Scott, Unfortunately, the manufacturer does not list a screw for the circulation motor. If you are able to get one of the screws then try to take it to the local hardware and see if you can get it. Read More...
Ed U March 28, 2020 for Model Number LG7932ST Here's a zinger! LE appears at different times during wash. Reset electric, dishwasher then won't start or circulation motor surges. Replaced circulation motor and diverter motor. Reassembled hooked up started. Started fine, fills, washed then went into I.E Reset tried again started ran they half cycle went into OE. Dishwasher fills and drains fine so not sure why codes come up. Ran 2 more times now LE code comes up. I check wiring in door nothing frayed or burnt. Thinking this all points now to PCB, that's another $200. Just about ready to buy a new dishwasher. Any last ideas? Thanks
1 Answer ED, There are several things to check with all you have going on. An IE error code signifies that the washing machine is filling with water slowly or not at all. This can occur when water supply taps are not fully open or the water pressure to the tap or house is too low. ... Other possible causes are kinked, pinched or bent water line hoses, or clogged water inlet filters. OE error indicates a DRAIN ISSUE. This means when the LG dishwasher gets to the time for it to drain out water, it is not draining correctly or cannot drain. This is caused by a CLOGGED DRAIN HOSE or a CLOGGED OR FAULTY DRAIN PUMP. The LE error code on the LG dishwasher display is an indication of a MOTOR ERROR. The 5 issues that may cause this fault code is a wiring problem (the the most common reason for LE error), the impeller of the washing pump is locked, the rotor of the washing motor is locked, the blade is locked, or the "Main PCB Control Board is faulty."

Ed July 27, 2019 for Model Number Ldf6920st The dishwasher is making a high pitched whining noise about 2 minutes after normal wash startup. The noise starts slowly and then within a few seconds accelerates quickly and the noise gets louder. Then everything stops. No error is displayed. Upon opening the dishwasher, the water pan is full, and it appears that the top spray arm moved, but don't believe the bottom spray arm moved? I know the drain pump is working (continuity between pins, and watched the water drain into garbage disposal about 45 seconds into cycle startup that was left in the pan from a prior run when I stopped the cycle director the noise). Took the unit apart looking for "anything" unusual, and thought I found the issue as I found a small piece of wood (like wicker?) By the chopping blade. So I removed it , put everything back together, and thought I found the problem...but unfortunately not. The noise did come again, but did take slightly longer after cycle startup for the noise to begin....maybe 3 minutes instead of 2. I took off the circulation pump, but don't know how to test it to see if it's bad, or if the problem is the diverter or other? The impeller will spin freely and has no broken fins. The smaller white piece (valve) by the diverter I cannot turn by hand. Not sure if that's normal? Need help. Not certain what to order, (circulation pump, diverter, valve, other??? and,/or how to test the suspect part prior to ordering a replacement. Thanks for your help.
1 Answer Ed, the diverter 4681ED3001D should not move freely by hand as it is a motor-driven gear. It would be unlikely that the valve would be causing the issue due to the fact that the unit shuts down after a few minutes. The most likely items that are going to cause this noise is either going to be the motor windings 4681ED1004B, or an electrical issue in the main control 6871DD1006Q. The main control can be inspected for any signs of electrical burning, unfortunately, the manufacturer does not list the winding resistance for the motor. The best way to identify what would be causing the issue is to locate the specific section where the noise is originating from, as well as checking for any error codes on the display. Read More...
Mathew October 28, 2018 I have a lg lds5040st and it keeps showing error code ne. the bottom rack gets clean but the top rack doesn't get clean at all. What is the issue
1 Answer Matthew, We are not showing this error code but with the bottom rack getting clean but the top rack not then this would most likely be caused by the diverter motor 4681ED3001D. Read More...
